Description Glenn Adams 2012-03-18 08:40:32 UTC
in 3.2.2 appears "The type of the attribute must not be a nullable or non-nullable sequence type, and it must not be a union type if one of its member types (or one of its member types’s member types, and so on) is a nullable or non-nullable sequence type."

is it not redundant to say "nullable or non-nullable sequence type" when "sequence type" would suffice? or is not the case that "nullable or non-nullable" is tautologous? if it is not, then an example is sorely needed
Comment 1 Cameron McCormack 2012-03-19 08:43:16 UTC
I use "sequence type" to mean the same thing as "non-nullable sequence type".  I used the phrase "nullable or non-nullable sequence type" because I thought "(potentially nullable) sequence type" or similar would be confusing.

I think I will go through and replace instances of "nullable or non-nullable X" with "X or nullable X".
